The answer to the given notation is 1970
What is standard notation ?Any value between 1.0 and 10.0 that can be expressed as a decimal number and multiplied by a power of 10 is referred to as being in standard form. If you look closely, you will see that 1.23 is a decimal between 1.0 and 10.0, and as a result, we have the standard form of 123,000,000 as 1.23 108.
This is already an standard notation : 1.97 × 10³
10 raised to the power three means there are three zeroes.
thus if we were to solve this question it will be
1.97 × 1000
which is equal to 1970.00
= 1970 .

this is for geometry can someone please help me find the missing angles?
Answer:
x = 50° , y = 40°
Step-by-step explanation:
x and 40° form a right angle and sum to 90° , that is
x + 40° = 90° ( subtract 40° from both sides )
x = 50°
x and y form a right angle and sum to 90° , then
x + y = 90°
50° + y = 90° ( subtract 50° from both sides )
y = 40°

What is a discount?Discounts are price cuts made by store owners on goods or services that would otherwise be sold for the indicated price. Usually, this portion of the rebate is given to increase sales or get rid of extra inventory. The List Price, sometimes referred to as the Marked Price, is the cost of a product as declared by the seller or manufacturer, excluding any discounts.
The final price at which a product is actually sold is the selling price, which includes any discounts or price drops from the list price. Off or reductions are frequent terms used to describe discounts. Note that the marked price of the item is always used to calculate the discount (list price).

Justin is playing tennis. When serving, he stands 12 feet away from the net, which is 3 feet tall. The ball is served from a height of 7.5 feet. Justin thinks the ball travels about 21.4 feet before it hits the ground 8 feet from the net on the opposite side.
a) How far does the ball travel?
b) What assumptions did you make to solve the distance the ball travels?
c) What mathematical practice did you use to solve this problem?
Considering Justin's serve, it is found that:
a) The ball traveled 21.4 feet, which means that Justin's estimate is correct.
b) An assumption regarding the angle of Justin's serve was made.
c) The Pythagorean Theorem was used to solve this mathematical problem.
Pythagorean TheoremThe Pythagorean Theorem relates the length of the legs [tex]l_1[/tex] and [tex]l_2[/tex] of a right triangle(triangle which has an angle of 90º between the two legs) with the length of the hypotenuse h, stating that the hypotenuse squared is the sum of the legs squared, according to the following rule:
[tex]h^2 = l_1^2 + l_2^2[/tex]
Assuming that the ball was served at an angle of 90º, the situation can be summarized as follows:
Distance of the serve: hypotenuse of the triangle.Bottom leg: horizontal change, of 20 feet, 12 feet on one side of the net and 8 feet on the other side of the net. Top leg: vertical change, of 7.5 feet, as the serve was made at a height of 7.5 feet, and hit the ground, where the height is of 0.Hence the Pythagorean Theorem is applied and the distance is calculated as follows:
d² = 7.5² + 20²
d = sqrt(7.5² + 20²)
d = 21.4 feet.

The function y= (x - 4)^2 + 3 is a transformation of the function y = x^2 . How is the function’s vertex affected by the transformation?
The transformation has a horizontal shift right by 4 units and vertical shift upwards by 3 units.
What do you mean by transformation of a function ?
The modification of a graphed function to create a different version of the parent function is known as transformation.
For the given condition :
The function is y = (x - 4)² + 3.
The above function is transformed from the parent function which is y = x².
We know that , the horizontal shift depends on the value of h. The horizontal shift and it is described as:
y = f (x + h)
Then , the graph of function will be shifted to left by h units.
and
y = f (x - h)
Then , the graph of function will be shifted to right by h units.
If we compare both functions i.e., y = (x - 4)² and y = f (x - h), their is a difference of -1 , it meant shift is right by 4 units.
Now , we know that , the vertical shift depends on the value of k. The vertical shift is described as:
y = f(x) + k
Then , the graph of function will be shifted up by k units.
and
y = f(x) - k
Then , the graph of function will be shifted down by k units.
Here , if we compare functions i.e., y = (x - 4)² + 3 and y = y = f(x) - k , we find out that the graph of function will be shifted upwards by 3 units.
Therefore , the transformation has a horizontal shift right by 4 units and vertical shift upwards by 3 units.

Two separate questions. 100 points for both answered. Brainliest if both answered.
Answer:
1.) 88 cones were sold
2.) $17.00 per gal of paint; $5.50 per brush
Step-by-step explanation:
1.) ($1.10(88)= $96.80) + ($2.35(84)= $197.40)= $294.20
2.) I have a really complicated process, and it's really late at night where I am
Answer:
For the first question, 88 cones were sold
For the second question, a gallon of paint costs 17 dollars and a brush costs 5.5 dollars (that is, 5 dollars and 50 cents).
Step-by-step explanation:
For the first question,
Let the number of ice cream cones be represented by the letter 'x'
And the number of sundaes be represented by the letter 'y'
[tex](1.10x + 2.35y) = 294.20 \: \: \: equ.2 \\ (x + y) = 172 \: \: \: equ.1[/tex]
Solving it simultaneously, subtract equ. 2 from equ. 1
[tex]0.10x - 1.35y = 122.20[/tex]
Making x the subject,
[tex]x = \frac{122.20 + 1.35y}{0.10} [/tex]
Substitute the value of x above in equ. 1
[tex] \frac{122.20 + 1.35y}{0.10} + y = 172[/tex]
L. C. M = 0.10
Multiply through by the L. C. M
[tex]122.20 + 1.35y + 0.10y = 17.2[/tex]
Collect like terms
122.20 - 17.2 = - 1.35y - 0.10y
105 = - 1.25y
[tex]y = \frac{105}{1.25} = 84[/tex]
Substituting the value of y in equ. 1
[tex]x + 84 = 172 \\ x = 172 - 84 \\ x = 88[/tex]
Therefore, 84 sundaes were sold and 88 ice-cream cones were sold.
For the second question, let paint represent 'p' and brush represent 'b'
[tex]8p + 3b = 152.5 \: \: \: equ2 \\ 6p + 2b = 113 \: \: \: equ1[/tex]
Solving simultaneously,
Subtract equ2 from equ 1
[tex]2p + b = 39.5 \\ b = 39.5 - 2p[/tex]
Substituting the value of b in equ1
[tex]6p + 2(39.5 - 2p) = 113 \\ 6p + 79 - 4p = 113[/tex]
Collect like terms
[tex]2p = 113 - 79 \\ 2p = 34 \\ p = 17[/tex]
Substituting the value of p in equ1
[tex]6(17) + 2b = 113 \\ 102 + 2b = 113[/tex]
Collect like terms
[tex]2b = 113 - 102 \\ 2b = 11 \\ b = 11 \div 2 \\ b = 5.5[/tex]
Therefore, a gallon of paint costs 17 dollars and a brush costs 5.5 dollars (i.e 5 dollars, 50 cents)

-6(6x - 1) +9=36x + 18
Answer:
x = - 1 / 24
Step-by-step explanation:
-6 ( 6x - 1 ) + 9 = 36x + 18
First, solve the brackets.
-36x + 6 + 9 = 36x + 18
Then, subtract 36x by both sides.
-36x - 36x + 6 + 9 = 18
-72x + 15 = 18
Now, Subtract 15 by both sides.
-72x = 18 - 15
-72x = 3
Now divide both sides -72 by both sides.
x = - 3 / 72
x = - 1 / 24

The half-life of an isotope is characterized as the sum of time it takes for there to be half the beginning sum of the radioactive isotope present.
since we know for half time
N = N₀(1/2) n ..........1
where n is the new amount whereas N₀ is the initial amount and n is the number of half time
since the ratio of 14c:12c is 1/16
so the equation 1 gets converted to
N/No =(1/2)n

I REALLY NEED HELP PLEASE THIS WORK IS FOR MONDAY.can y’all please help me:(
Answer:
Step-by-step explanation:
To find the cost of the apples, simply multiply the cost by how much Derek buys. So: 3.8 * 1.35= 5.13.
So, For Part A the answer is A.
For Part B: We need to find the total cost of both apples and oranges. We already know the total cost of apples is 5.13. We need to find the cost of oranges.
We multiply:
5.2* 1.45= 7.54
Now, add the totals together: 7.54+5.13
The total is 12.67.
If Derek payed with a 20 dollar bill, we would subtract 20 with 12.67.
The answer is 7.33. So the answer is A.
